Thanks Andrian for the hint on the Node.JS libraries. I am sticking to the Java and Kotling environment for various reasons.
I've been reading about the R2RML Ontop API for Java. But to my limited knowledge it seams geared towards queering and transforming relational DB (JDBC) to RFD and not trough merging tabular data with RDF model.

In case you still want to do it on your own for whatever reason I would recommend our CSV on the Web based parser, which is streaming-capable. GTFS generates a *lot* of data so streaming is a must. https://github.com/rdf-ext/rdf-parser-csvw This is for example used here: https://github.com/zazuko/blv-tierseuchen-ld Node.js based, not JVM. regards Adrian
